Automotive flock and its significance in forensic fibre examinations

The interiors of fifty eight vehicles were examined and samples were taken. All vehicles had samples of flocked material in their interiors. Flocked material was found on the window channels, window frames, door edges and in glove compartments or central console compartments. The majority of flock fibres used in the vehicles examined were carbon black pigmented polyester or nylon. A variety of dyed nylon fibres were also used in the vehicles. The discrimination power of dyed flock fibres used in the interior of vehicles was found to be 0.974. The front seats of these vehicles were examined for loose flock fibres. All vehicles had flock fibres present on the front seats. In the majority of vehicles, flock originating from material in the vehicle's interior was present on the front seats of the vehicle. The number of flock fibres present on the front seats varied greatly from car to car but did not appear to be dependant on the type of seat fabric or on which areas in the car were flocked.     

A population study of polyurethane foam fragments recovered from the surface of 100 outer-garments

One hundred outer-garments were examined for microscopic fragments of polyurethane foam. Low power stereomicroscopy was used to classify fragments into 18 groups according to macroscopic colour. Amber, pale yellow and black were the most frequently encountered, whilst navy, pale blue, bright pink, beige, brown, pale green, peach and white were the least frequently encountered. High power comparison/fluorescence microscopy was used to discriminate 166 populations within 16 colour groupings. The majority (95.2%) of populations consisted of three fragments or less. This study demonstrates that the background population of foam fragments on an outer-garment consists of low numbers representing various colours. Therefore, finding a large population of microscopically indistinguishable fragments within a casework situation has the potential to be considered highly significant evidentially.     

Haplotype analysis for Irish ancestry

Forensic haplotype analysis of the male Y chromosome is currently used to establish the number of male donors in sexual assaults, the number of male bleeders in blood pattern analysis, and for ancestry correlation to genetic founder populations in biogeographic studies. In forensic laboratory applications, its primary use is for DNA profile generation with trace amounts of male DNA in the presence of excess female DNA (e.g. spermatozoa identification, male component of fingernail scrapings). Our study supports the potential use of the Y chromosome in a “dragnet” approach (most haplotypes are unique) similar to that described by Kayser in 2017 for solving a cold case sex assault and homicide in The Netherlands. Our study also researched the potential for the identification of an ancestral Irish genetic “footprint” linked to surname O’Brien and identified multiple founder group origins in Ireland and England as well as three samples with the Dal Riata (a Gaelic overkingdom) ancestral haplotype. This study indicates correlation to ancestral Irish ancestry by haplotype but not conclusively to the O’Brien surname.     

Turnover among City Managers: The Role of Political and Economic Change

Executive turnover can have profound effects on city policies, programs, and commitments such as contracting or issuing debt. This article identifies how political changes, reflected in the composition of the city council, and economic changes in the community influence city manager turnover. Analysis of manager turnover patterns in 143 large U.S. cities with council-manager governments from 1987 to 1999 allows us to distinguish "push" and "pull" factors that can induce city managers to leave their jobs. The empirical analysis demonstrates that political conflict and economic development can influence the likelihood that a city manager will exit a community, but these effects can be complex. In particular, the influence of community economic development on turnover includes a temporal dimension not revealed in previous research. We conclude by discussing the findings' implications for career patterns in city management.     

Fibre mapping--a case study.

Fibre mapping, more commonly known as one-to-one taping, was developed in Germany approximately twenty years ago. The technique facilitates the distribution of fibres on a surface to be recorded. The impact of this technique on the investigation of serious crime has been reported in the European Fibre Group on several occasions. This paper represents a case study of the application of the technique. It is believed to be the first time that this technique has been successfully applied in the United Kingdom.     

Space Weapons: Alternatives for Today

The massive budgets for U.S. military space and missile defense represent the beginning stages of a new arms race in space. But with the United States facing record budget deficits and record defense spending and with the international community expressing increasing concerns about the weaponization of space, the next administration faces some real questions about how hard it wants to push for new attack weapons in space.

No matter how the upcoming U.S. presidential election turns out, the next administration faces dilemmas with respect to the lack of a justifying threat, the technical difficulty and cost of placing weapons in space, how far its international partners want to go with missile defense and with weapons in space, and, finally, the type of international negotiations in which it is willing to engage. Each of these situations creates alternatives for today, alternatives which the next U.S. President will confront and the international community can and should engage.     

Chilling Journalism: Can Newsgathering be Harassment or Stalking?

Newsgathering often requires journalists to ask uncomfortable questions or make multiple attempts to talk to unwilling sources. Some journalists have been accused of harassment, even when the plain language of state laws would not classify their actions as criminal conduct. In the rare instances that journalists actually were charged with harassment or subject to protective orders for stalking, district attorneys or judges typically did not allow them to be punished. This study, however, found nine statutes that might be applied to punish newsgathering activities that are neither hounding nor harassing. It also identifies language from statutes that clearly could not be applied to punish newsgathering communications by journalists. The article recommends that prosecutors and judges continue to prevent the application of criminal harassment and stalking laws to newsgathering activities.
